Abstract

La présente invention concerne un procédé de fabrication d'une souche de levure faisant intervenir L-arabinose, destinée à la production d'éthanol, une souche de levure étant modifiée par introduction et expression du gène <i>araA </i> (L-arabinose isomérase), du gène <i>araB</i> (L-ribulokinase D?121¿-N) et du gène <i>araD</i> (L-ribulose-5-P 4-épimérase), et mise en oeuvre de mutations supplémentaires dans son génome ou surexpression d'un gène <i>TAL1</i> (transaldolase) de manière que ladite levure consomme L-arabinose. Ainsi, ladite levure peut être employée comme l'unique source de carbone et pour la production d'éthanol. L'invention concerne également un procédé de production d'éthanol faisant intervenir une telle souche modifiée.
